Every cookware surface has its own set of rules to guarantee correctly cooking food and a long life on your shelf. Whether your cabinets are stocked with nonstick, cast iron or stainless steel (or you’re thinking about a set to invest in), these tips will keep your pots and pans properly cared for.

1. Nonstick
When cooking with nonstick pans use medium heat or lower. High heat on a coated pan will shorten its shelf life. Because temperatures can soar, don’t preheat an empty pan. Add food or even oil from the start. Keep in mind that foods prepared in a nonstick pan will not brown well, as high heat is necessary for a seared surface to develop. Foods won’t be able to adhere to the surface and form the browned bits that make up a golden crust.
